HAIRPIN.

Application filed March 13, 1918, Serial No. 222,067. Renewed August 12, 1920.

To (ZZZ whom it may concern.

Be it known that I, Josnrrr 1L. BnoWNn, a citizen of the United States of America, and resident of lvlountain Lakes, in the county of iilorris and State of New Jersey, have invented certain new and useful Improvements in l-lairpins of which the following is a specification.

My invention relates to an improvement in hair pins.

I have illustrated said invention in the accompanying drawing referring-to like parts by like numerals.

Figure l is a front elevation, and Fig. 2 a side elevation.

The hair pin is formed from two sections of spring wire or it may be made oi any other material that is adapted to take and retain the form indicated and have the qual ity of elasticity in the sense of spring, when a resistant object as a mass of hair is interposed between the arms. I will however describe it as made of wire.

Two sections of wire as l and 2 are twisted I i am aware that hair pins of this general type. that is, comprising two bifurcated.

members one included within the other, is known in the art. I therefore do not intend to claim such structures broadly, but only in a limited sense to cover the particular arrangement curvatures for each bifurcated member in its relation to the other bifurcated member. For example, in the structure as illustrated in the member re--a, I provide two bulging sections as a-a', (6 -66 with a depressed section between them as (t -af The ends or termini are also formed to diverge as indicated. So in forming the smaller bifurcated member I provide a bulged section as at b-Z" and a depressed section as at b b and the termini of section b are turned outwardly that is diverge, as indicated at b -b Specification of Letters Patent.

Patented Nov. 30, 1920.

Serial No. 403,139.

In operation the hair when the pin is introduced passes between the arms aa, thence between the arms b b and also is forced between the outer wall of the inner member )7) and the inner walls of the outer member c-a. When all of this space is filled with strands of hair, the two members aa and b t) cooperate to grip the hair between them, and the ropes or masses-of hair which are thus held are restrained from slipping out, because of the irregular form of the two bifurcated members, that is to say, a portion of: the hair is held within the arms 6-?) and within the bulged section a a and a'a and prevented from slipping out by the pressure exerted between said members a and b, for it will be understood that when the hair pin is forced into the hair a great mass of hair is forced between the arms of said members by reason of their divergent termini and they are of necessity forced to expand, the spring metal or material of which they are formed permitting a certain yielding incident to said operation. Hence the mass of l ar is subject to said spring or elastic pressure, and it is confined within said bulging sections and between the inner and outer bifurcated members.

hat I claim is:

A hair pin formed from two sections of wire twisted together adjacent one end of each to form a union between them and to form two bifurcated members one longer than the other the shorter inclosed within the longer and both in substantially the same plane the longer member having two bulg ing sections and two depressed sections with diverging termini, while the shorter member has one bulging section and one depressed section with diverging termini, the shorter member situated adjacent the head of the pin, with its curvatures corresponding substantially with the curvatures of the longer member adjacent thereto, its divergent termini expanding into a bulged section.
